To all whom t may concern:

Be it known that we, OsKAR TANDLER and GUsrAv TANDLER, both citizens of Germany, and residents of Crimmitschau, in Sachsen, Germany, have jointly invented new and useful Improvements in lVarp Holders, of which the following is a specification.

Our invention relates to an adjustable and exchangeable warp-holder` for clothlooms and dressing machines and the object of our invention is to provide for a construction and arrangement of parts, as hereinafter described and set forth, in which the disadvantages, also hereinafter set forth, are avoided.

In describing our invention we refer to the drawing herewith in which Figure l is a plan view of our new construction, Figure 2 is a longitudinal section through the same and Figures 3, 4f, 5, 6, 7, 8 are detail views.

As will be understood from the following, our invention relates to the connection only of the warp with the beam-canvas and for this reason this portion of the loom is illustrated only, while the loom itself we presume as already known and requiring no illustration. j

ln looms it was customary heretofore to employ a pair of iron rods for suspending the warp-end from the beam-canvas and to connect these two rods with each other by sewing or Stringing together. To one of the rods the canvas would be attached and to the other the warp. rlhis way of connecting the warp with the canvas, while it facilitates in starting winding up the warp upon the warp-beam, has various disadvantages, For instance, whenever in finishing the cord connecting the two rods should tear or become loose, there will be slightly defective spots in the product which will render the latter saleable only as inferior quality at a considerably reduced price. Much depends on the place or spot where the cord begins to tear or break or to become loose. llhenever this happens at the warp-beam, one or two yards will always be useless which means a decided loss for the manufacturer, as well as for the weaver.

Another drawback is that by sewing the rods to the canvas and the connection of the rods in the way heretofore customary, the canvas would in course of time become so full of holes that it had to be cut oil as entirely useless. The new sewing-in of and to the warp are connectable with each other by detachable metal-holders of great tensile strength and durability, thus permitting an undisturbed operation of the loom for many years. riccordinglyv the tractive force will thus be transmitted from the canvas upon the warp no more by means of'a cord or other libre product, but by metal, in this instance, by rotatably supported holders, which are by means of adjustable adjusting-rings secured in their respective positions. lThe rods consist of telescopic parts and may by extending and contracting be fitted to every width, an eX- change of those rods being no more required.

The warp a is secured on the beam 7) and, respectively, the rod o in the heretofore known way. So is the canvas attached on the one hand to the beam c and on the other to the rod f, this being done by bending round and sewing-on the ends. ln the side where the rod f is provided, the canvas has notches g which may be edged in the way, as is customary with button holes, to prevent a fringing-out of the cloth, the rod f being thus exhibited through these notches. Within these notches g there are the holders 7L of metal attached to the rod f and connecting the latter with the corresponding rod c of the warp c. The holders 7L maybe made up each of a strip of sheet-metal, so bent that eyelets z' are formed, adapted to receive the two rods c and f, the free ends of the strip of sheetmetal bearing on the stay la and being kept together on and with the same by movable collars Z, also made up of a suitably bent strip of sheet metal. To permit of an easier opening or closing of one or both eyes 'i after the withdrawal of the collar Z, the strip of sheet metal may be cut, both parts being rotarily kept together by a hinge m. In this way the portion of the eye, which is, in fact, a cover or lid, permits an easy opening or, respectively, closing, thus, there will be secured a speedy and at the same time convenient attachment of the holders 7L to the rods c and y.

The respective ends of the rods c and f may be connected by another kind of holders a, differing from the holders 7b and consisting of a piece of wire each, also bent in such way that a pair of eyelets o are formed, one of the said eyelets to bc hooked in a hole p in the rod f while the other eyelet may be slipped over the rod c. To prevent a slipping of the holder a from the rod an adjusting-ring Qy may be put on each of the ends of the said rod c, movable on the same and adjustable in any place by means of a screw 11.

The warp-beam c may be provided with an axial groove or recess s to receive the rods and holders and to prevent the latter from forming projecting parts on the said beam. The length of the canvas should be suited to the diameter of the beam c, so that during the winding-up rods and holders re- 'main exactly in the recess or groove s.

In the stay 7c of the holder 7L there are holes or recesses t while in the lid there are corresponding projections a which may be attained by impressing or punching the material. Then the holder is closed, the said projections a engage the said recesses t and prevent a lateral displacement of the hingedly connected parts of the holder.

The secureinent of the canvas to the warpbeam c is done in the followingway: In the groove s there are at certain distances from each other and by screws w secured curved strips e of metal. In the said strips fv there is a longitudinal slot e containing a screw having ahead and nut. The' canvas should be laid upon the metal-strips i), the grooves d engaging the screws After putting on a metal slab o the nuts of the screw m should be drawn on. By the longitudinal slot in the metal strip o the canvas may be so adjusted that the rods e, f will together with the holders come to be embedded in the groove s.

lVhenever it is desired to malre fabrics of a larger width the bands for the extension in width of the canvas may be easily moved upon the aforesaid metal slab or bar.

Instead of the external holders a the afore-mentioned holders 71, may as well be employed which may be secured against dropping or slipping by inwardly pointing projections going into the holes .a provided in the rods c, f.

The above described connection between the canvas and warp has the advantage that the tensile power is from the canvas transmitted through the holders It and a, while no such power acts against any threads or cords that may still be present. Accordingly, the connection is extremely durable and a. loosening, tearing or breaking of the meetings which would happen heretofore, cannot occur any more. The meeting or joint itself may be easily brought about within a short time by means of the holders.

The rods e, f are consisting each of a sleeve or collar c', j in which a pair of rods 0, f may be axially moved, thus permitting their lengthwise adjustment to the intended width of the fabric. If required the collar or sleeve c or f may be lengthwise slotted and bear slot-ted clamping-rings or flaps, by the drawing on of which the rods c, will be clamped fast in their respective sleeve or collar. l/Vhenever a weaver has finished, both rods may be secured to the beam, ready for the next employment. The holders described may be used also in dressing machines.

IVe cla-im 1. In a warp holder, in combination, a rod adapted to be attached to the end of a warp, a second rod adapted to be secured to the beam by flexible means, releasable metal clamps connecting said rods and consisting each of a metal strip so bent as to form hinged eyelets on both its ends, slidable nietal collars adapted to engage the ends of said strip, and hold said clamps in a clamping position, and disengageable metal clips adapted to connect the ends of said rods, substantially as set forth.

2. l warp holder of the type specified in claim l, in which said rods are telescopic, substantially as set forth.

3. In a warp holder of the type specified in claim l, comprising a groove in the beam; a metal strip adapted to secure the flexible means releasably in said groove, the connecting members between warp and said flexible means adapte-d to be received in the said groove upon rotation of the beam, substantially as set forth.
